[WIP] Package cppcheck as snap app

[gocarlos]

packaged the cppcheck gui as snap app.

By packaging this app as snap app, one can reach most linux distributions with only one app and the app runs in a sandbox.
Furthermore one can also release beta and edge (tracking git master) channels.

It's still not size optimized...

[gocarlos]

This app is already released to the snap store. Can be tested with

sudo snap install cppcheckgui

I can also transfer the ownership of the snap app, so you can release the app into the stable channel when you wish. (master branch is released to edge channel automatically)

Other than that, travis can also produce automatically snap apps and release then to the release section on this page (same as msi packages for windows)
